A recent result of Moshkovitz cite{Moshkovitz14} presented an ingenious method to provide a completely elementary proof of the Parallel Repetition Theorem for certain projection games via a construction called fortification. However, the construction used in cite{Moshkovitz14} to fortify arbitrary label cover instances using an arbitrary extractor is insufficient to prove parallel repetition. In this paper, we provide a fix by using a stronger graph that we call fortifiers. Fortifiers are graphs that have both 1 and 2 guarantees on induced distributions from large subsets. We then show that an expander with sufficient spectral gap, or a bi-regular extractor with stronger parameters (the latter is also the construction used in an independent update cite{Moshkovitz15} of cite{Moshkovitz14} with an alternate argument), is a good fortifier. We also show that using a fortifier (in particular 2 guarantees) is necessary for obtaining the robustness required for fortification.
